There are many different potions that replace Health (HP). Most replace an amount immediately and then a smaller amount each tick over a period of time. These are called Heal Over Time (HOT) potions. The second, rarer, type heals a large amount instantly. Instants usually heal more but if the amount healed is more than you need the extra is wasted, while HOTs repair the damage as it is still coming in, tending to waste less.

The table below shows all the Health Potions, their type, worth, and effects.
